WINDIVIILL ATTACHMENT.

SPECIFICATION forming part of Letters Patent N o. 734,494, dated July 28, 1903.

Application filed August 5, 1901. Serial No. 70.886. (No model T0 all whom, t may concern.-

Beit known that I, CHARLES S. AITKEN, residing at Plankinton, in the county of Aurora .and State of South Dakota, have invented certain useful Improvements in Windmill Attachments; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which forma windmill-tower provided with my windmill attachment. Fig. 2 shows a top View, with portions removed, of my attachment. Fig. 3 shows a detail of one of the pawls,`while Fig. 4 shows a detail of the guide-plate used in my invention.

In the accompanying drawings, 2 and 3 show the uprights of an ordinary windmill-l tower, while 4 represents one of the crossbraces. Secured to one or more of the crossbraces 4t of an ordinary windmill-tower is a base-frame comprising the end bars 5 and 5" and the side bars 6 and 6'lto form a rectangular frame. Extending upward from this base-frame are the posts 7 7' and 8 8'. The end posts 7 and S are connected by means of the frame-bar 30, while the posts or uprights 7' 8' are connected by the frame member 30', the members and 40' being interposed between the frame members 30 30', as is more clearly shown in Fig. 2. Secured to the baseframe member 6' is an upright or standard 13, which extends upward a suitable distance and gives support to the shaft H, which shaft upon the opposite side is supported by means of the hanger L, secured, by means of the pin Z', to the upperside frame member 30. This shaft H is provided with a y-wheel G upon one end and with the belt or chain pulley I upon the opposite end. Near the.' fly-wheel G this shaft is further provided with a gearwheel 28, which meshes with a gear-wheel F, secured to the drive-shaft D. This driveshaft D is secured to and works within the upper end of the hanger L, as is shown in Fig'. 1, and upon the opposite end works within the bearing L', secured to the transnverse frame member 30', as is shownin Fig. 2. 'To this shaft D is secured the large driving-gear F. Approximately intermediate of its length this shaft, which is prevented rfrom workingout laterally by means of the collars fand f', is provided with the collars 26 and 27, from the first of which extends the armB and from the second of which extends the arm B', and interposed between these arms B and B' is the ratchet-wheel E, as shown.

In Fig. 3 is shown aldetail of the arm B', which is similartothe one marked B. At one end each of the arms B and B' is provided with the pin e and a dog, the rst arm B being provided'with'the dog C and the arm B' with the dog or pawl C', as is shown in Fig. 3. It will be noticed that the pawl C engages the ratchet E from below, referring to Fig. I, while the pawl or dog C' engages the ratchet E from above. A spring 23 is hooked-about each arm B and B in such a manner lthat the upper end works down ,upon the pawl, so as to force these pawls C and C into engagement with the ratchet E. These arms B B" are rocked upward and-downward by means of the arms A A', secured to the arms byv means of pins 21, one arm being shown in detail in Fig. 3. These arms A A' are in the form of hangers and below by means of a bolt b, secured by means of a nut c, are secured to a rocker-arm 14, which arm 14 works upon a pin a, held within the bearing l2, as is clearly shown. This rocker-arm 14 is provided with a number of openings as. At its free end this rockerarm is provided with a pin 15, to which is secured a link 16, which link 16 is held by means of a pin 17, which pin 17 formsapart of the clamping-collar 18, secured by means of the screws 19, so that this clamping-collar may be adjustably secured tothe reciprocating pump-rod 20, as shown.

Positioned adjacent the standards 8 8' is a guide-plate 9, provided with the incision 24 IOS and the slots 25 25. Secured to the frame member 5 are suitable bolts which pass through the slots 25, and these bolts are secured by means of the nuts 32, so that this guide-plate '9 may be raised and lowered. The rocker-arm 14 works within the slot- 24 of the plate 9, and by reason of said slot said arm is prevented moving laterally upon its -fulcrum ct, and accurate vertical movem ent of the arms A and A is thusinsured. MoreY over, by adjustably mounting the plate 9, through the medium of the slots 25 and bolts 32, upon the frame member 5 said plate 9 may be readily raised or lowered to accord with the change of pitch of the arm I4 when its fulcrum-point is changed through the medepresses the lever lll to raise the arm A', so-

that the pawl C engages the ratchet E to rotate the shaft D. At the end of the stroke the hangers descend and the hanger A operates the pawl C to turn the ratchet F, so that as the hangers rise and fall they operate the pawls to engage and revolve the ratchet E, and this rotary movement is imparted to the large gear-wheel F, by means of which it is transferred to the power-shaft H, which is given a steady movement by virtue of the heavy ily-wheel G, secured to the shaft H, and from which shaft the poweris transferred, by means of a belt connection, to a suitable machine.

The device is simple of construction and can be attached to any machine which is provided with a bar.

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

1. In an 'attachment of the class described,

the combination with a supporting-frame, a power-shaft journaled thereon, a drivingshaft also journaled upon said frame and geared to said power-shaft for driving the latter, and ratchet mechanism for actuating said driving-shaft, of a rocker-arm carried by said frame and having an adjustable fulcrum thereon,`said rocker-arm having suitable connections for attachment to a reciprocating element to receive motion therefrom,and aguideplate carried by said supporting-frame and having a slot in which said rocker-arm reciprocates, whereby said rocker-arm is prevented moving laterally upon its fulcrum,said guideplate being vertically adjustable upon said frame, whereby said plate may be raised or lowered to accord with the change of pitch of the rocker-arm when the fulcrum-point of the latter is changed.

2. In an attachment of the class described, the combination with a supporting-frame, a power-shaft journaled thereon, a drivingshaft also journaled upon said frame and geared to said power-shaft for driving the latter, a ratchet-wheel mounted upon said driving-shaft, reversely-arranged pawls engaging said ratchetwheel for actuating the same, and arms for actuating said pawls,of a rockerarm carried by said frame and having an adjustable fulcrum thereon, said rocker-arm having suitable connections for attachment to a reciprocating element to receive motion therefrom, and a guide-plate carried by said supporting-frame and having a slotin which said rocker-arm reciprocates, whereby said rocker arm is prevented moving laterally 'upon its fulcrum, said guide-plate being vertically adjustable upon said frame, whereby said plate may he raised or lowered to accord with the change of pitch of the rocker-arm when the fulcrum point of the latter is changed.
